Morningstar SunSaver 20A 12V Solar Charge Controller with LVD

The Morningstar SunSaver 20L is an industrial-grade 12V solar charge controller designed to deliver highly reliable power management for both professional and consumer off-grid applications. Engineered to outperform standard PWM controllers, this 20A unit provides precise charging control, protecting your valuable battery banks from overcharging while ensuring maximum energy harvest from your solar array.

Advanced Battery Protection and Low Voltage Disconnect

A standout feature of this model is the integrated Low Voltage Disconnect (LVD). Deep discharging is one of the leading causes of premature battery failure in off-grid solar systems. The SunSaver actively monitors your 12V battery bank and will automatically disconnect dedicated DC loads before the voltage drops to critical levels. This significantly extends battery lifespan and reduces the risk of being stranded without power in remote locations. Additionally, a removable jumper allows installers to easily select between sealed or flooded lead-acid battery profiles for precise charging.

Solving the Generic Controller Problem

Many generic solar charge controllers struggle with inconsistent voltage regulation and poor thermal management, leading to battery degradation and unpredictable system shutdowns. The SunSaver resolves these issues by utilising advanced solid-state design and a highly efficient PWM algorithm. This ensures that your 12V batteries receive a clean, tightly regulated charge, completely eliminating mechanical relay failures. By maintaining optimal battery health, you avoid the costly and frustrating process of premature battery replacement.

Certified for Hazardous Locations and Extreme Conditions

Unlike standard charge controllers that can fail under extreme heat or coastal humidity, the SunSaver is built for the harshest environments. It is fully rated for Hazardous Locations (Class 1, Division 2 Groups A-D), making it the industry standard for oil and gas applications, telecommunications, and remote monitoring stations. The rugged anodised aluminium mounting flange provides secure installation and superior heat dissipation, ensuring stable operation even in extreme Australian conditions. This durability also makes it a premium choice for marine vessels, caravans, and 4WD setups.

Intuitive Status Monitoring and Secure Connections

System monitoring is made straightforward via clear LED status indicators, which display charging status, temperature sensor activity, and battery state of charge at a glance. Installation is highly secure thanks to large, heavy-duty screw terminals designed to easily accommodate thick solar input and battery cables, minimising voltage drop and eliminating loose connections.

Key Features

  • Low Voltage Disconnect (LVD): Automatically disconnects loads to prevent damaging deep battery discharges.
  • Hazardous Location Certification: Class 1, Division 2 Groups A-D rated for critical industrial and remote applications.
  • Selectable Battery Profiles: Easily switch between sealed and flooded lead-acid charging via a simple jumper.
  • Clear LED Diagnostics: Instant visual feedback for system status, charging, and overall battery health.
  • Rugged Construction: Features a durable anodised aluminium mounting flange for marine, RV, and industrial use.
  • Heavy-Duty Terminals: Large screw terminals ensure secure, low-resistance connections for solar and battery cables.

Secure Your Off-Grid Power System

When system failure is not an option, investing in high-quality charge management is essential. The Morningstar SunSaver 20A provides the reliability and advanced protection needed for demanding environments, reducing maintenance risks and protecting your battery investments. Equip your 12V solar array with industry-leading control and order your Morningstar SunSaver today.

BUY THIS ONE!
Model: NewSLS50_52
This is one of the good ones. There are other brands just as good, and manny brands are worse, but this handles well, rolls down easily, doesn't come off at all easily, and adapts to dips and curves like a champ. Appropriately heavy and dead, I'm happy with the way it smothers panel resonances and even at muffling direct sound, like a big hand over my Uncle Harry's eternally noisy mouth. You can rip the foil but you have to work hard at doing that. Remember to buy a brayer; you can roll overlaps nice and thin. Also remember to pre-wipe the sheet metal with a decent solvent like acetone or Stoddard/Varsol. It should last forever.

Good stuff, but watch the temp
Model: NewSLS50_52
I used this in my single cab pickup truck (89 ford.) It only took half the box (10 sheets or 25 square feet) to do the floors, but I bought the big box because I plan to do the doors, back wall, and maybe the roof as well. One thing I learned is that the temperature matters when you’re doing the installation. It was around 55F when I started in the evening, and when it dipped down into the 40s the sheets would not stick to the metal, and were hard to compress with the roller. That’s why I ended up only doing the floors and not any vertical surfaces; i will have to wait for a nice hot day. The other thing is that the foil layer on top is razor sharp at the edges, definitely wear gloves! I didn’t notice until after but I have little papercuts all over my fingers. Aside from those things, the install was easy and straightforward. The sheets cut easily with scissors, and any goo that ends up on your hands or scissors can be cleaned up with acetone (nail polish remover), or lacquer thinner. I would use this stuff again.

The Mitt is it.
I ordered the applicator because the Poli Glow Kit on hand was ordered and received a couple of years ago and it had the old chamois covered rectangular applicator. I could tell by looking that the mitt was the better solution. Also, the mitt was described well in an online video, so using it was easy to learn. The results were fantastic and I am very pleased with it. The only thing I would change is to add some more information on how often to replenish the mitt and with how much Poli Glow liquid. I wasn't sure if I was skimping or wasting the material. As I approached halfway, I couldn't tell if I was going to run out before I finished, so I tried to be as frugal as possible. Turns out, I had liquid left over.
